4mm x 20mm Pozi Flanged PT30 Screw for Soft Plastics | A2 Stainless Steel
Suitable for lighting housings and plastic bezels, this 4mm x 20mm Pozi Flanged screw uses the PT30 thread profile developed for plastics. The narrow 30° flank angle helps limit outward boss stress while the 8.0mm head diameter provides a broad bearing surface over the assembly.
What Are Pozi Flanged PT30 Screws?
Pozi Flanged PT30 screws are designed for moulded or predrilled pilot holes in softer plastics such as polypropylene, ABS, LDPE and Nylon. The PZ2 drive uses a widely available tool format while the larger head diameter spreads clamping force over more of the component surface.
Common Applications
- Manufactured Plastic Parts: Supports repeatable assembly of injection-moulded components with correctly designed pilot holes.
- Plastic Enclosures: Fastens covers and panels while the wide flange spreads bearing pressure over the enclosure surface.
- Appliance Housings: Provides a dedicated plastic fastening method for covers, panels and moulded appliance components.
- Furniture Components: Secures suitable moulded plastic fittings and panels used in furniture manufacture.
